Fig. 5From: Chemerin 156F, generated by chymase cleavage of prochemerin, is elevated in joint fluids of arthritis patientsSchematic of chemerin cleavages. Chem163S (pink box) can be cleaved either by factor XIa (FXIa), Plasmin, or Tryptase generating chem158K (pink box), by elastase generating a mixture of chem157S (red box) and chem155A (blue box), by chymase generating chem156F (dark pink box), or by proteinase 3 and Tryptase generating chem155A. chem158K can then be cleaved by carboxypeptidase B2 (CPB2) or carboxypeptidase N (CPN) to form active chem157S, which is subsequently inactivated by angiotensin-converting enzyme (ACE) forming inactive chem155ABack to article page
